Abstract

A food cooking appliance such as a waffle maker, pizza maker or toaster uses a combination of sensor inputs and optional user preferences to determine an optimal cooking time.

First claim

What is claimed is:

1. An electrical waffle making device comprising: a base that is connected to an upper housing with a hinge; the upper housing having a handle and an upper cooking plate and the base supporting a lower cooking plate, the upper and lower cooking plates forming a cavity when brought together, wherein the cavity is arranged to receive batter for making a waffle, and wherein
the lower cooking plate includes an outer rim and a continuous peripheral moat adjacent to and surrounding the outer rim and wherein the peripheral moat is arranged to contain excess batter flowing over the outer rim, a portion of the outer rim extending to an edge of a shoulder;
the peripheral moat formed adjacent to where the upper and lower cooking plates are brought together to meet at the edge, wherein a bead extending from one of the cooking plates contacts the edge of the other of the cooking plates, the peripheral moat sized so as to remain exposed and uncovered by the upper housing when the upper and lower cooking plates are brought together;
the hinge arranged to allow the upper housing to float in parallel with the base; and
wherein the hinge includes lower hinge elements that are integral with the lower plate, and a pair of upper hinge elements engaging the lower hinge elements, the hinge having a pin at a rear pivot location and a pin at an intermediate pivot location on the upper hinge elements, and wherein the lower hinge elements are located outwardly of the peripheral moat.

2. The device of claim 1 , wherein:
the peripheral moat has an internal radius of at least 5 mm.

3. The device of claim 1 , wherein:
the peripheral moat has an internal radius of 5 mm to 11 mm.

4. The device of claim 1 , wherein:
the peripheral moat has an internal radius of 11 mm or larger.

5. The device of claim 1 , wherein:
a ratio of a volume of the peripheral moat to a volume of the waffle cooked by the device is between 1:4.9 and 1:10.

6. The device of claim 1 , wherein:
a pivot is disposed between the upper and lower hinge elements and above the peripheral moat.

7. The device of claim 1 , wherein:
the upper hinge elements are interconnected by a bracket.

8. The device of claim 1 , wherein:
an extent of a parallel separation between the upper cooking plate and the lower cooking plate is limited by a bumper formed on an upper surface of the upper cooking plate that contacts the hinge.

9. The device of claim 1 , wherein:
a lock mechanism extends between the upper housing and the peripheral moat.

10. The device of claim 9 , wherein:
the lock mechanism is retained by the handle.

11. The device of claim 1 wherein:
a ratio of a volume of the peripheral moat to a volume of the waffle cooked by the device is more than 1:4.9.

12. The device of claim 1 wherein:
a ratio of a volume of the peripheral moat to a volume of the waffle cooked by the device is 1:4.9.

13. The device of claim 1 , wherein:
the peripheral moat is integral with the lower cooking plate.

14. The device of claim 1 , wherein:
the peripheral moat has a cross-section being in the shape of a semi-circle.

15. The device of claim 1 , wherein:
the peripheral moat is continuous.

16. The device of claim 1 , wherein:
the upper cooking plate or the lower cooking plate includes a vertically-extending rim defining at least a portion of the outer rim of the cavity.

17. An electrical waffle making device comprising:
a base is connected to an upper housing with a hinge;
the upper housing having a handle and an upper cooking plate and the base supporting a lower cooking plate, the upper and lower cooking plates forming a cavity when brought together, wherein the cavity is arranged to receive batter for making a waffle;
an outer rim of the lower plate extending to a shoulder formed at an uppermost portion of the lower cooking plate adjacent an outer edge of the cavity, the shoulder being where the upper and lower cooking plates are brought together, the lower cooking plate having a continuous peripheral moat arranged to contain excess batter flowing over the rim;
the peripheral moat formed adjacent to and outwardly of the outer rim and the shoulder, with the peripheral moat being disposed below the peripheral shoulder, the peripheral moat sized so as to remain exposed and uncovered by the upper housing when the upper and lower cooking plates are brought together at a bead extending from the upper cooking plate contacting the shoulder of the lower cooking plate; and
the hinge arranged to allow the upper housing to float in parallel with the base.

18. The device of claim 17 , wherein the hinge includes lower hinge elements that are integral with the lower plate, and a pair of upper hinge elements engaging the lower hinge elements, the hinge having a pin at a rear pivot location and a pin at an intermediate pivot location on the pair of upper hinge elements, and wherein the lower hinge elements are located outwardly of the peripheral moat.

19. The device of claim 17 , wherein:
a pivot is disposed between the upper and lower hinge elements and above the peripheral moat.

20. The device of claim 17 , wherein:
the upper hinge elements are interconnected by a bracket.

21. The device of claim 17 , wherein:
an extent of a parallel separation between the upper cooking plate and the lower cooking plate is limited by a bumper formed on an upper surface of the upper cooking plate that contacts the hinge.

22. The device of claim 17 , wherein:
a lock mechanism extends between the upper housing and the peripheral moat, and wherein the lock mechanism is retained by the handle.
